Transcribed Image Text:

The ultrashort laser pulse has its peak intensity at 550 nm (in vacuum). Coating a piece of glass (N glass= 1.52) with a 250 nm thick film of transparent material of unknown refractive index (except that it's between N glass <N film <2.50) and hitting the film with your laser, you notice that the film seems to be reflecting nearly all the 550-nm light. Use this to determine the most likely index of refraction for the film.
